Abstract

This invention provides a narrow-frame curtain wall unit panel and a narrow-frame curtain wall installation structure. The narrow-frame curtain wall unit panel includes an outer frame, a light-transmitting panel, and a light source. The outer frame has a through-hole, with an inner sidewall formed on the inner side and an outer sidewall formed on the outer side. One end of the inner sidewall has a first groove surrounding the frame opening. The other end of the outer sidewall has a second groove, which allows the outer frame to connect to the keel. The light-transmitting panel is disposed in the frame opening, with its outer edge extending into and connecting with the first groove. The light source is disposed in the first groove and located on the outer periphery of the light-transmitting panel. The first and second grooves in the narrow-frame curtain wall unit panel provided by this invention can be spaced apart, allowing the connector to directly avoid the first groove when engaging with the second groove, thus preventing interference with the installation of the light source within the first groove. This adapts to narrow-frame designs and reduces construction difficulty.

Description

Technical Field

[0001] This invention belongs to the field of curtain wall technology, specifically relating to a narrow-frame curtain wall unit panel and a narrow-frame curtain wall installation structure. Background Technology

[0002] With the rapid development of the field of architectural engineering technology, narrow-frame curtain walls are becoming increasingly popular due to their high splicing precision, strong styling expression, and high degree of architectural freedom. Narrow-frame curtain walls are formed by splicing multiple narrow-frame unit panels, which have unique styling expression and visual aesthetics, and are widely used in various landmark buildings (usually connected to the keel on the outside of the building) and large-scale public facility projects.

[0003] In existing technologies, curtain walls, in addition to their aesthetic appeal, typically require lighting to further enhance their visual quality, especially at night. Narrow-frame unit panels generally consist of an outer frame and panels fixed to the inside of the outer frame. When connecting the narrow-frame unit panels to the keel, the outer frame is usually fixed to the keel using connectors. However, with narrow-frame unit panels, after the connectors are installed, interference may occur inside the outer frame, potentially preventing the placement of light sources, especially for continuous strip light strips. This necessitates placing the light sources on the keel or in other locations, affecting aesthetics and increasing the difficulty of light source placement and construction. Summary of the Invention

[0004] This invention provides a narrow-frame curtain wall unit panel and a narrow-frame curtain wall installation structure, which aims to solve the problem that the existing narrow-frame curtain wall unit panels cause increased construction difficulty and affect aesthetics due to interference between the narrow-frame design and the arrangement of light sources.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] On one hand, a narrow-bezel curtain wall unit panel is provided, comprising:

[0007] The outer frame has a through opening, and the through direction of the opening is set as a preset direction. An inner wall is formed on the inner side of the outer frame inside the opening, and an outer wall is formed on the outer side of the outer frame opposite to the inner wall. Along the preset direction, the outer frame has a first end and a second end. A first groove is provided on the inner wall near the first end, and the first groove is arranged around the opening. A second groove is provided on the outer wall near the second end, and the second groove is used for connecting the outer frame to the keel.

[0008] A light-transmitting plate is disposed in the frame opening, and the outer edge of the light-transmitting plate extends into the first groove and forms a connection with the first groove;

[0009] The light source is arranged in the first groove and located on the outer periphery of the light-transmitting plate.

[0010] In one possible implementation, the outer frame includes multiple border units, which are connected end to end in sequence to form a polygonal / irregular shape.

[0011] In one possible implementation, each of the border units includes:

[0012] The main frame has two opposing first side walls and two opposing second side walls, with the first side walls and the second side walls being perpendicular to each other; one of the second side walls is used to contact the keel, and the other second side wall is provided with an outwardly extending extension plate, the end of which is provided with a first hook; the second groove is located on the main frame.

[0013] A sub-frame is disposed on the side of the main frame away from the keel. The sub-frame has a narrow side plate opposite to the second side wall and an exposed plate that abuts against the extension plate. The narrow side plate forms the first groove between itself and the second side wall of the main frame away from the keel. The end of the exposed plate is provided with a limiting end that abuts against the extension plate. The exposed plate is also provided with a second hook that engages with the first hook.

[0014] In one possible implementation, the light source is fixed to the extension plate.

[0015] In one possible implementation, a first rubber pad is provided between the narrow side plate and the light-transmitting plate; a second rubber pad is provided between the second side wall surface away from the keel and the light-transmitting plate.

[0016] Lin Yifang also provides a narrow frame curtain wall installation structure, including several narrow frame curtain wall unit panels as described above and several assembly and connection components evenly arranged on the keel; process seams are formed between any two adjacent narrow frame curtain wall unit panels, and the narrow frame curtain wall unit panels are combined to form a curtain wall.

[0017] Each of the assembly and connection components corresponds to multiple narrow-frame curtain wall unit panels, each of the narrow-frame curtain wall unit panels is arranged around the assembly and connection component, and each of the narrow-frame curtain wall unit panels has a corner that intersects with the assembly and connection component.

[0018] Each of the assembly and connection components has a limiting part, which is used to provide vertical support for the narrow frame curtain wall unit panel corresponding to the assembly and connection component; each of the assembly and connection components also has multiple pressing parts, each pressing part is adapted to the second groove in the corresponding narrow frame curtain wall unit panel, and each pressing part is used to cooperate with the limiting part to press the corresponding narrow frame curtain wall unit panel onto the keel in the normal direction of the formed curtain wall.

[0019] In one possible implementation, each of the assembled connecting components includes:

[0020] An edge support member is detachably connected to the keel, and the edge support member has multiple slots; each slot is used for the corner of a portion of the narrow frame curtain wall unit panel to be inserted to support the portion of the narrow frame curtain wall unit panel; the edge support member is the limiting part;

[0021] The central locking fastener is located on the side of the edge support away from the keel and is detachably connected to the keel. The central locking fastener has multiple support arms, which are arranged in a ring at intervals. Each support arm corresponds one-to-one with each of the corresponding narrow-frame curtain wall unit panels, and each support arm extends into a second groove provided on the corresponding narrow-frame curtain wall unit panel. The support arm is the pressing part. After the central locking fastener is connected to the keel, it presses the corresponding narrow-frame curtain wall unit panels onto the keel by having each of the support arms extend into the second groove.

[0022] In one possible implementation, the edge support is connected to the keel by a first screw; the center locking member is connected to the keel by a second screw.

[0023] The device includes two first screws, which are spaced apart horizontally; and one second screw, which is located between the two first screws and passes through a hole in the edge support to connect with the keel.

[0024] In one possible implementation, each of the narrow-frame curtain wall unit panels surrounding any one of the assembled connecting components forms a panel unit, and the axis around which each panel unit is surrounded is a central axis; a plane horizontally passing through the central axis is defined as a dividing plane; each of the narrow-frame curtain wall unit panels above the dividing plane is a first panel;

[0025] In the edge support member corresponding to each plate unit, the number of the slots corresponds one-to-one with the number of each first plate, and each slot is located above the dividing surface, and each slot is used for each first plate to be inserted.

[0026] In one possible implementation, the width of each support arm is smaller than the width of the process seam; wherein, the central locking fastener is used to be inserted through the intersection of each narrow frame curtain wall unit panel after the corresponding panel unit is fixed, and to rotate each support arm into each of the second grooves respectively.

[0027] The narrow-frame curtain wall unit panel provided in this implementation, compared with the prior art, has a first groove on the inner sidewall of the frame and a second groove on the outer sidewall. The first groove is located on the inner sidewall of the outer frame near the first end and is arranged around the frame opening. The second groove is located on the outer sidewall of the outer frame near the second end. The first and second grooves can be spaced apart in a preset direction, so that when the connector engages with the second groove, it can directly avoid the first groove, avoiding interference with the installation of the light source within the first groove, while also adapting to the narrow-frame design. The outer edge of the light-transmitting panel extends into the first groove and connects with it. The first groove, through its groove structure, forms a wrapping fixation on the outer edge of the light-transmitting panel, improving the firmness of the connection between the light-transmitting panel and the outer frame. The light source is directly arranged within the first groove and located on the outer periphery of the light-transmitting panel, with the light source hidden inside the frame, eliminating the abruptness of exposed light sources and maximizing visual aesthetics. Moreover, the light source is integrated into the first recess, eliminating the need for on-site positioning, fixing, and wiring of the light source for the keel. The light source and the outer frame can be pre-installed in the factory, reducing on-site construction procedures and lowering the operational and construction difficulty of light source placement.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] The directions or similar terms used throughout this invention, such as "front," "back," "left," "right," "top," "bottom," "inner," "outer," and "side," are mainly for reference to the directions in the accompanying drawings. These directions or similar terms are only used to assist in explaining and understanding the embodiments of this invention and are not intended to limit this invention.

[0044] This invention provides a narrow-frame curtain wall unit panel, please refer to it as well. Figure 1 and Figure 2The narrow-frame curtain wall unit panel provided by the present invention will now be described. The narrow-frame curtain wall unit panel includes an outer frame 10, a light-transmitting panel 20, and a light source 30. The outer frame 10 has a through-hole, and the through-hole direction is set to a preset direction. An inner sidewall is formed on the inner side of the outer frame 10 within the through-hole, and an outer sidewall is formed on the outer side of the outer frame 10 opposite to the inner sidewall. Along the preset direction, the outer frame 10 has a first end and a second end. A first groove 12 is provided on the inner sidewall near the first end, and the first groove 12 is arranged around the through-hole. A second groove 13 is provided on the outer sidewall near the second end, and the second groove 13 allows the outer frame 10 to connect to the keel 50. The light-transmitting panel 20 is disposed in the through-hole, and the outer edge of the light-transmitting panel 20 extends into the first groove 12 and is connected to the first groove 12. The light source 30 is disposed in the first groove 12 and is located on the outer periphery of the light-transmitting panel 20.

[0045] It should be explained that the shape of the frame in this embodiment can be an equilateral triangle, a regular square, a regular hexagon, etc. The second groove 13 can form two opposing inner walls. After the narrow frame curtain wall unit panels are arranged on the keel 50, the two opposing inner walls are spaced apart along the normal direction of the curtain wall. The inner wall closer to the keel 50 can be used for fixing of the connectors or application of fastening force to fix the narrow frame curtain wall unit panels.

[0046] It should be noted that the shape of the light-transmitting plate 20 can be adapted to the shape of the frame, and the light-transmitting plate 20 can be an acrylic plate. The outer edge of the light-transmitting plate 20 extends into the first groove 12, but does not fill the first groove 12 completely. There is a certain gap between the outer edge of the light-transmitting plate 20 and the bottom surface of the first groove 12 to ensure that space is provided for the fixed installation of the light source 30.

[0047] The narrow-frame curtain wall unit panel provided in this embodiment has a first groove 12 on the inner sidewall of the frame and a second groove 13 on the outer sidewall of the frame. The first groove 12 is located on the inner sidewall of the outer frame 10 near the first end and is arranged around the frame opening. The second groove 13 is located on the outer sidewall of the outer frame 10 near the second end. The first groove 12 and the second groove 13 can be spaced apart in a preset direction, so that when the connector is engaged with the second groove 13, it can directly avoid the first groove 12, avoiding interference with the installation of the light source 30 in the first groove 12, while also adapting to the narrow frame design. The outer edge of the light-transmitting plate 20 extends into the first groove 12 and connects with it. The first groove 12 forms a wrap-around fixation on the outer edge of the light-transmitting plate 20 through the groove structure, improving the firmness of the connection between the light-transmitting plate 20 and the outer frame 10. The light source 30 is directly arranged in the first groove 12 and located on the outer periphery of the light-transmitting plate 20. The light source 30 is hidden inside the frame, without the abruptness of the exposed light source 30, maximizing the visual aesthetics. Moreover, the light source 30 is integrated into the first groove 12, eliminating the need for separate positioning, fixing, and wiring of the light source 30 on the construction site for the keel 50. The pre-installation of the light source 30 and the outer frame 10 can be completed in the factory, which can reduce on-site construction procedures and reduce the operational and construction difficulty of arranging the light source 30.

[0048] In some embodiments, the outer frame 10 may be as follows: Figure 1 The structure shown is as follows. The outer frame 10 includes multiple border units 11, which are connected end to end in sequence to form a polygonal / irregular shape.

[0049] The outer frame 10 is composed of multiple frame units 11 connected end to end in sequence. According to the design requirements of the curtain wall, the number, length and connection angle of the frame units 11 can be adjusted to flexibly splice them into polygonal structures such as triangles, rectangles, and hexagons, which enhances the expressive freedom of the curtain wall and can adapt to the personalized and differentiated appearance design requirements of various landmark buildings and large public facilities, thereby strengthening the uniqueness and recognizability of the building.

[0050] Moreover, the frame unit 11 can adopt a standardized design and be mass-produced through a unified mold, eliminating the need for separate mold processing for each polygonal or irregularly shaped frame 10, thus reducing the production difficulty and investment cost of irregularly shaped frames 10.

[0051] In some embodiments, the aforementioned border may be as follows: Figure 2The structure is shown. Each frame unit 11 includes a main frame 111 and a sub-frame 112. The main frame 111 has two opposing first side walls and two opposing second side walls, with the first and second side walls perpendicular to each other. One of the second side walls can contact the keel 50, and the other second side wall has an outwardly extending extension plate 113, with a first hook 114 at the end of the extension plate 113. A second groove 13 is located on the main frame 111. The sub-frame 112 is located on the side of the main frame 111 away from the keel 50. The sub-frame 112 has a narrow side plate 115 opposite to the second side wall and an exposed plate 116 that abuts against the extension plate 113. A first groove 12 is formed between the narrow side plate 115 and the second side wall of the main frame 111 away from the keel 50. The exposed plate 116 has a limiting end 117 that abuts against the extension plate 113 at its end, and the exposed plate 116 also has a second hook 118 that engages with the first hook 114.

[0052] It should be noted that the sub-frame 112 has a narrow side plate 115 and an exposed plate 116. In one possible implementation, the narrow side plate 115 is arranged parallel to the second side wall, while the exposed plate 116 is arranged parallel to the extension plate 113. The second hook 118 is located on the exposed plate 116 and is located at the middle position of the exposed plate 116. When the second hook 118 is engaged with the first hook 114, the limiting end 117 at the end of the exposed plate 116 will abut against the extension plate 113 to restrict the rotational freedom of the sub-frame 112, thereby ensuring that the narrow side plate 115 in the sub-frame 112 remains parallel and spaced apart from the second side wall, ensuring the formation of the first groove 12.

[0053] In this embodiment, the main frame 111 primarily bears the structural load and connects to the keel 50, while the sub-frame 112 primarily houses the light source 30 and the light-transmitting panel 20. The sub-frame 112 and the main frame 111 are detachably connected, allowing for structural optimization to meet different needs and facilitating manufacturing. One second sidewall of the main frame 111 can directly contact the surface of the keel 50, making the connection between the main frame 111 and the keel 50 more secure. When the connector fixes the main frame 111 to the keel 50 through the second groove 13, the stress is more evenly distributed. The first hook 114 of the extension plate 113 of the main frame 111 and the second hook 118 of the exposed plate 116 of the sub-frame 112 are interlocked. With the limiting end 117 of the exposed plate 116 and the abutment and limiting of the extension plate 113, the main frame 111 and the sub-frame 112 can be detachably connected without the use of bolts, welding or other additional fasteners. This facilitates the installation of the light-transmitting plate 20 and the light source 30.

[0054] In some embodiments, the light source 30 may be as follows: Figure 2 The structure shown. The light source 30 is fixed on the extension plate 113.

[0055] The extension plate 113 is an integrally formed structure of the main frame 111, with sufficient structural strength and rigidity. The light source 30 is directly fixed on the extension plate 113, and the installation foundation is stable, ensuring the stability and safety of the light source 30 during operation.

[0056] In addition, the extension plate 113 is spaced from the outer edge of the light-transmitting plate 20. The plate surface of the extension plate 113 away from the first hook 114 will serve as the bottom surface of the first groove 12. The light source 30 is fixed on this plate surface to ensure that the light beam can pass through the outer edge of the light-transmitting plate 20 and enter the light-transmitting plate 20.

[0057] In some embodiments, the first groove 12 and the light-transmitting plate 20 may be provided with an arrangement such as Figure 2 The structure is shown. A first rubber pad 21 is provided between the narrow side plate 115 and the light-transmitting plate 20. A second rubber pad 22 is provided between the second side wall surface away from the keel 50 and the light-transmitting plate 20.

[0058] The first rubber pad 21 is disposed between the narrow side plate 115 of the sub-frame 112 and the light-transmitting plate 20, and the second rubber pad 22 is disposed between the second side wall of the main frame 111 away from the keel 50 and the light-transmitting plate 20. That is, the first rubber pad 21 and the second rubber pad 22 are distributed on both sides of the light-transmitting plate 20. Both the first rubber pad 21 and the second rubber pad 22 are made of flexible materials to avoid direct rigid contact between the light-transmitting plate 20 and the outer frame 10, such as a metal frame, thereby preventing damage to the light-transmitting plate 20 and ensuring the safety of the light-transmitting plate 20 in use.

[0059] Meanwhile, the first rubber pad 21 and the second rubber pad 22 have good elasticity and extensibility, which can adapt to the thermal expansion and contraction deformation of the light-transmitting plate 20 and the outer frame 10 caused by temperature changes, and buffer the stress caused by deformation. Moreover, the first rubber pad 21 and the second rubber pad 22 tightly fill the gap between the outer edge of the light-transmitting plate 20 and the first groove 12, which can prevent external dust, water vapor, rainwater, debris and other objects from entering the interior of the first groove 12, protect the light source 30, and thus ensure the light emission effect.

[0060] Based on the same inventive concept, this application also provides a narrow-frame curtain wall installation structure, which can be found in [reference needed]. Figure 3 , Figure 7 and Figure 8The narrow-frame curtain wall installation structure includes several narrow-frame curtain wall unit panels as described above and several assembly connection components 40 evenly arranged on the keel 50. A process seam 14 is formed between any two adjacent narrow-frame curtain wall unit panels, and the narrow-frame curtain wall unit panels are combined to form the curtain wall. Each assembly connection component 40 corresponds to multiple narrow-frame curtain wall unit panels, each narrow-frame curtain wall unit panel is arranged around the assembly connection component 40, and each narrow-frame curtain wall unit panel has a corner 15 that intersects with the assembly connection component 40. Each assembly connection component 40 has a limiting part, which can vertically support the corresponding portion of the narrow-frame curtain wall unit panel. Each assembly connection component 40 also has multiple pressing parts, each pressing part is adapted to the second groove 13 in the corresponding narrow-frame curtain wall unit panel, and each pressing part, in conjunction with the limiting part, can press the corresponding narrow-frame curtain wall unit panel onto the keel 50 in the normal direction of the formed curtain wall.

[0061] It is important to understand that the assembly of multiple narrow-frame curtain wall unit panels often employs traditional exposed connectors or welding methods. Therefore, the following problems arise during actual installation: First, in narrow-frame scenarios, the gaps between adjacent narrow-frame curtain wall unit panels are typically only millimeters in size. This severely limits the operational space of traditional assembly methods, making precise installation and adjustment difficult, resulting in high construction difficulty and low installation efficiency. Second, exposed connectors disrupt the integrity and continuity of the curtain wall surface, affecting the overall aesthetics of the building and failing to meet the requirements of seamless design in high-end buildings. Third, traditional connection methods typically involve directly connecting the outer edge of the narrow-frame curtain wall unit panel to the keel 50, requiring the arrangement of openings and connectors. This approach is unsuitable for narrow-frame designs, and the large number of connectors required results in a large number of keels 50, leading to higher costs.

[0062] Based on this, in the narrow-frame curtain wall installation structure provided in this embodiment, each assembly connection component 40 corresponds to multiple narrow-frame curtain wall unit panels, and each narrow-frame curtain wall unit panel is arranged around the assembly connection component 40. The limiting part of each assembly connection component 40 can ensure support for each narrow-frame curtain wall unit panel, so as to ensure that a uniform process seam 14 is formed between each pair of narrow-frame curtain wall unit panels. Each assembly connection component 40 can serve as an intersection point for multiple narrow-frame curtain wall unit panels to be arranged around it, and can also provide vertical support for the surrounding narrow-frame curtain wall unit panels. Multiple assembly connection components 40 can ensure that each narrow-frame curtain wall unit panel is vertically supported simultaneously. Each assembly connection component 40 limits and fixes the multiple narrow-frame curtain wall unit panels corresponding to it in the normal direction of the curtain wall through each clamping part. This installation structure can accommodate millimeter-level process joints 14 and achieves uniform load transfer, ensuring stability between each narrow-frame curtain wall unit panel, preventing loosening or detachment of the panels, extending the overall service life of the curtain wall, reducing construction difficulty, and improving installation efficiency. Simultaneously, the assembly connection components 40 are located within the process joints 14, with no exposed parts, thus not occupying additional space on the curtain wall facade and maintaining aesthetics. Furthermore, by setting the assembly connection components 40 at the corners 15 of the narrow-frame curtain wall unit panels, nodal stress is achieved, changing the way the narrow-frame curtain wall unit panels are connected to the keel 50 via the outer edge, adapting to narrow frames; this structure also significantly reduces the number of connection points between the narrow-frame curtain wall unit panels and the keel 50, effectively reducing the amount of keel 50 used and lowering costs.

[0063] In addition, the narrow frame curtain wall installation structure provided in this embodiment also has all the technical effects brought about by the narrow frame curtain wall unit panels.

[0064] It should be noted that the curtain wall is typically mounted on the keel 50, which is the basis for the curtain wall installation. Each narrow-frame curtain wall unit panel can have multiple corners 15, such as a triangular panel with three corners 15. Specifically, for a single assembly connection component 40, each of the multiple narrow-frame curtain wall unit panels has a corner 15 corresponding to that assembly connection component 40. That is, the assembly connection component 40 corresponds to multiple corners 15 where the multiple narrow-frame curtain wall unit panels intersect. See [reference needed]. Figure 8Each assembly connection component 40 is surrounded by multiple narrow-frame curtain wall unit panels, and can provide vertical support for the surrounding narrow-frame curtain wall unit panels. Each assembly connection component 40 simultaneously provides vertical support for each narrow-frame curtain wall unit panel to ensure that a process joint 14 can be formed between any two adjacent narrow-frame curtain wall unit panels. The clamping part can press each narrow-frame curtain wall unit panel onto the keel 50 in the normal direction of the curtain wall, or together with the keel 50, clamp the narrow-frame curtain wall unit panels to fix them in the normal direction of the formed curtain wall.

[0065] In this embodiment, the irregularly shaped unit plate can be an equilateral triangle shape, a square shape, a hexagon shape, etc.

[0066] In addition, the connection points are formed only by assembling the connection components 40, so the number of connection points will be greatly reduced. Moreover, the keel 50 does not need to be arranged according to the outer edge of the narrow frame curtain wall unit panel during the laying process, which can reduce the amount of keel 50 used, as well as reduce the construction difficulty and amount of keel 50, and save costs.

[0067] In some embodiments, the aforementioned assembly connection component 40 may employ, for example... Figure 3 and Figure 4 , Figure 6 and Figure 7 The structure is shown. Each assembly connection component 40 includes an edge support 41 and a center locking fastener 42. The edge support 41 is detachably connected to the keel 50 and has multiple slots 411. Each slot 411 allows the corners 15 of some narrow-frame curtain wall unit panels to be engaged to support them. The edge support 41 serves as a limiting part. The center locking fastener 42 is located on the side of the edge support 41 away from the keel 50 and is detachably connected to the keel 50. The center locking fastener 42 has multiple support arms 421, which are arranged in a ring at intervals. Each support arm 421 corresponds one-to-one with a corresponding narrow-frame curtain wall unit panel, and each support arm 421 extends into a second groove 13 provided on the corresponding narrow-frame curtain wall unit panel. The support arm 421 serves as a clamping part. After the center locking fastener 42 can be connected to the keel 50, it extends into each of the second grooves 13 through each support arm 421, so as to press the corresponding narrow frame curtain wall unit panels onto the keel 50 through one inner wall of the second groove 13.

[0068] The edge support 41, through multiple latches 411, enables rapid insertion and positioning of the corners 15 of the narrow-frame curtain wall unit panels, reducing installation difficulty in narrow process seams 14 and improving assembly accuracy and construction efficiency. Simultaneously, both the edge support 41 and the central locking fastener 42 are detachable, facilitating later disassembly, maintenance, and replacement of the panels. The support arms 421 formed by the central locking fastener 42 extend into the second groove 13 to form a fitted engagement, ensuring uniform clamping force on the narrow-frame curtain wall unit panels in the normal direction of the curtain wall. This ensures that the edge support 41 limits the positioning of each narrow-frame curtain wall unit panel, while avoiding excessive local stress, optimizing the load transfer path, and reducing stress concentration. Both the edge support 41 and the central locking fastener 42 are hidden inside the process seams 14 formed by the narrow-frame curtain wall unit panels, with no exposed structures, completely achieving a seamless curtain wall facade and ensuring aesthetics.

[0069] In this embodiment, the second groove 13 will form two opposing inner walls. The two opposing inner walls are spaced apart along the normal direction of the curtain wall. The inner wall near the keel 50 is used for the support arm 421 to abut. The solid part where the inner wall is located can also form a corner 15, or facilitate the formation of the corner 15. In addition, the thickness of the solid part where the inner wall is located is greater than or equal to the thickness of the edge support 41.

[0070] In some embodiments, the edge support 41 and the center locking fastener 42 may be adopted as follows: Figure 3 The structure is shown. The edge support 41 is connected to the keel 50 by a first screw 412. The center locking fastener 42 is connected to the keel 50 by a second screw 422.

[0071] The device includes two first screws 412, which are spaced apart horizontally. It also includes one second screw 422, located between the two first screws 412, which passes through a hole in the edge support member 41 and connects to the keel 50.

[0072] The detachable connection between the first screw 412 and the second screw 422 facilitates assembly, adapts to prefabricated construction, and improves installation efficiency. The two horizontally spaced first screws 412 increase the contact area of ​​the edge support 41, preventing its deflection or displacement and ensuring the positioning of the limiting part. The centrally located second screw 422 avoids interference with the two first screws 412, ensuring that the clamping force of the central locking fastener 42 is evenly distributed to each narrow-frame curtain wall unit panel, guaranteeing consistent clamping force on each support arm 421, and thus ensuring balanced force distribution on each narrow-frame curtain wall unit panel. The through-hole design prevents structural interference between the screws and the edge support 41, simplifying installation operations within the small space of the process seam 14. All first screws 412 and second screws 422 are built-in and not exposed on the curtain wall surface, further ensuring the integrity of the appearance, ensuring aesthetics, avoiding single-point fixing or edge overlap, ensuring the uniform transfer of load between each narrow frame curtain wall unit panel, thereby ensuring the stability between each narrow frame curtain wall unit panel, preventing each narrow frame curtain wall unit panel from loosening or falling off, and extending the overall service life of the curtain wall.

[0073] In some embodiments, the edge support 41 may be adopted as follows: Figures 3 to 5 The structure is shown. Each narrow-frame curtain wall unit panel surrounding any one of the assembly connection components 40 forms a panel unit, and the axis around which each panel unit surrounds is the central axis. The plane horizontally passing through the central axis is defined as the dividing plane. Each narrow-frame curtain wall unit panel above the dividing plane is the first panel.

[0074] Among them, the number of slots 411 in the edge support member 41 corresponding to each plate unit corresponds one-to-one with the number of each first plate, and each slot 411 is located above the dividing surface, and each slot 411 is used for each first plate to be inserted.

[0075] Since all unit panels are arranged vertically, and the resulting panel units are also arranged vertically, each edge support 41 provides multiple slots 411. Each slot 411 can fix the first panel located above the dividing surface. Specifically, one corner 15 of each first panel is inserted into the slot 411, thus fixing the first panel vertically. The narrow-frame curtain wall unit panels located below the first panels can be fixed to the lower edge support 41, also by having their corners 15 inserted into the slots 411. The fit between the slots 411 and the corners 15 of the narrow-frame curtain wall unit panels ensures the uniformity of the process seams 14, thereby ensuring the uniformity of the process seams 14 between the narrow-frame curtain wall unit panels.

[0076] In one possible implementation, each narrow-frame curtain wall unit panel has an equilateral triangular shape. Each panel unit comprises six narrow-frame curtain wall unit panels. The three upper narrow-frame curtain wall unit panels constitute the first panel.

[0077] The equilateral triangular narrow-frame curtain wall unit panels exhibit strong geometric stability, ensuring symmetry and aesthetic appeal. Each narrow-frame curtain wall unit panel has three sides 15, each with an angle of 60°. Therefore, six narrow-frame curtain wall unit panels are formed around a single assembly connector 40, arranged in a ring for a pleasing visual effect and aesthetically pleasing appearance. Correspondingly, three narrow-frame curtain wall unit panels are located above the segmented surface; these three panels constitute the first panel. The edge support 41 has three latches 411, each for inserting into one of the first panels.

[0078] In some embodiments, the aforementioned center locking fastener 42 may employ, for example... Figure 6 and Figure 7 The structure is shown. The width of each support arm 421 is smaller than the width of the process seam 14. The central locking fastener 42 can be inserted through the intersection of the narrow frame curtain wall unit panels after the corresponding panel unit is fixed, and each support arm 421 is inserted into the second groove 13 by rotation.

[0079] The support arm 421 is narrower than the process seam 14, adapting to the narrow process seam 14 and avoiding insufficient operating space during installation, thus facilitating the installation of the center locking fastener. The fact that the support arm 421 is narrower than the process seam 14 ensures that after each narrow-frame curtain wall unit panel is installed and forms a panel unit, the center locking fastener 42 can be installed. Simultaneously, the center locking fastener 42 can be inserted through each process seam 14 and, after rotation, positioned within the corresponding narrow-frame curtain wall unit panel. The structure of the support arm 421 adapting to each second groove 13 ensures that each support arm 421 can limit and fix each narrow-frame curtain wall unit panel in the normal direction of the curtain wall, thereby ensuring the locking of each narrow-frame curtain wall unit panel. This installation method simplifies the installation process, makes operation more convenient, and significantly improves installation efficiency. Furthermore, the rotational installation method allows adjustment of the clamping position of each support arm 421, ensuring the reliability of the clamping of the narrow-frame curtain wall unit panels.

[0080] In some embodiments, the edge support 41 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The edge support 41 is a stainless steel plate.

[0081] Stainless steel offers excellent corrosion resistance, making it suitable for complex outdoor environments, extending the service life of edge support components 41, and improving the overall durability of the curtain wall. The panel structure ensures high processing precision and accurate 411 bayonet dimensions, while its light weight reduces the overall load on the curtain wall.

[0082] In some embodiments, the edge support 41 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The center locking fastener 42 is made of stainless steel.

[0083] Stainless steel offers excellent corrosion resistance, making it suitable for complex outdoor environments and extending the service life of the central locking fasteners 42, thus improving the overall durability of the curtain wall. The panel structure ensures high processing precision, with accurate dimensions for the second groove 13, while its lightweight design reduces the overall load on the curtain wall.

[0084] In some embodiments, the process seam 14 described above can be adopted as follows: Figure 8 The structure shown. See also Figure 8 The width of process seam 14 is 8.5mm-9.5mm.

[0085] Preferably, the width of the process seam 14 is 9mm. This width range is considered a narrow frame, which not only meets the appearance design requirements of high-end buildings for a seamless narrow frame, but also provides suitable operating space for the internal installation of the assembly connection component 40 and the rotation insertion of the support arm 421. At the same time, this width of the process seam 14 ensures the accuracy of panel splicing and facilitates the formation of a uniform narrow process seam 14, making the curtain wall facade more concise and regular, and meeting the aesthetic design requirements of high-end buildings.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
